The NX3L1G66GM is a low-ohmic single-pole single-throw analog switch manufactured by NXP Semiconductors. It operates within a supply voltage range of 1.4 V to 4.3 V and features an active HIGH enable input with Schmitt trigger action for noise immunity. The device provides bidirectional signal transmission between two independent terminals (Y and Z) with minimal attenuation due to its low ON resistance, which ranges from 0.5 Ω to 1.6 Ω depending on the supply voltage. It supports continuous current handling up to 350 mA under a 3.3 V supply and includes robust ESD protection exceeding 7500 V via HBM standards.
Verify component authenticity through official NXP channels or authorized distributors. Confirm package integrity as the XSON6 form factor is sensitive to mechanical stress. Check manufacturing date codes against current availability status, as this specific part number may be subject to discontinuation notices. Ensure compliance with RoHS directives and REACH SVHC requirements before integration into final assemblies.
Select this component when designing circuits requiring low signal distortion in portable electronics. Verify that the operating temperature range meets system requirements, as the device is specified from -40 °C to +125 °C. Consider the XSON6 package dimensions for PCB layout constraints. Ensure supply voltage stability remains within the 1.4 V to 4.3 V limits to maintain optimal ON resistance performance.
This component belongs to the NX3L series of analog switches designed for space-constrained mobile applications. It serves as a bidirectional signal routing element controlled by a single digital input. The XSON6 package variant offers a compact footprint suitable for high-density board designs. It functions as a replacement for legacy SPST switches requiring lower insertion loss.
